Dog Training Job - Ruyterwacht, WC, 7460

Hello! I desperately need assistance with my 7 month old German shepherd. Lola is the most friendly dog I've come across. She knows the basics, like sit, down and go but for some strange reason all basic commands are ignored. Recall doesn't work anymore. She ALWAYS pulls when we take her for a walk. She does this more when my mom and daughter walk in front of her. She wants to lead. Generally starts jumping on people when they enter our home. Please advise if you can assist. I'm available every weekend, I work from home as well if that helps. I can start at the end of Feb when funds allow.
